Aesido Style Guide
The Gentleman's Guide to
Men's Suit Jackets
Dressing for Every Occasion
A well-chosen suit jacket is more than clothing — it is a statement of character, confidence, and taste. Whether you're commanding a boardroom, celebrating a milestone, or simply elevating your everyday look, the right jacket transforms how the world perceives you — and how you carry yourself within it.
Chapter 01
The Business Professional
Command the Room
In the professional arena, your suit jacket is your armor. The goal is authority without arrogance — precision without rigidity.
The Right Jacket
- Silhouette: Single-breasted, two-button, slim or tailored fit
- Fabric: Wool or wool-blend in charcoal grey, navy, or deep black
- Lapels: Notch lapels at a medium width — classic, never trendy
- Details: Minimal — clean chest pocket, functional sleeve buttons
How to Wear It
Pair with a crisp white or pale blue dress shirt, a silk tie in a complementary tone, and well-polished Oxford shoes. A pocket square in white linen adds quiet refinement.
“Dress for the role you want, not the role you have.”
Occasions — Board meetings · Client presentations · Interviews · Corporate events
Chapter 02
Black Tie & Formal Events
The Art of Evening Elegance
When the invitation reads black tie, there is only one answer: the tuxedo jacket. This is menswear at its most refined — a silhouette unchanged for over a century because it requires no improvement.
The Right Jacket
- Style: Single-breasted with peak or shawl lapels in satin or grosgrain
- Fabric: Fine wool, barathea, or velvet for winter galas
- Color: Midnight black or deep midnight navy
- Details: Satin-faced lapels, covered buttons, no exterior pockets
“Elegance is restraint. Resist the urge to personalize with novelty accessories.”
Occasions — Galas · Award ceremonies · Charity dinners · Opera · Formal weddings
Chapter 03
The Wedding
Celebrating in Style
Whether you are the groom, a groomsman, or a distinguished guest, a wedding calls for a jacket that balances celebration with sophistication. The season and setting are your primary guides.
Groom's Note
Consider a bespoke or made-to-measure jacket — this is the one occasion where the fit must be flawless. Every photograph will tell the story of how well you dressed.
Occasions — Wedding ceremonies · Receptions · Engagement parties · Civil ceremonies
Chapter 04
Business Casual & Social Occasions
The Versatile Blazer
The blazer — a suit jacket worn without its matching trousers — is the most versatile piece in a modern gentleman's wardrobe. It bridges the gap between formal and relaxed with effortless authority.
Pair It With
- Tailored chinos in stone, tan, or grey — never jeans unless explicitly casual
- A white or light blue OCBD shirt, open collar or with a knit tie
- Loafers or Derby shoes — clean, polished, never sneakers in a business context
“The blazer is the Swiss Army knife of menswear. Master it, and you are dressed for 80% of life's occasions.”
Occasions — Business casual offices · Client lunches · Dinner dates · Cocktail parties · Weekend travel
Chapter 05
Fit Is Everything
The Non-Negotiable Rule
No matter the occasion, no matter the fabric or color — fit is the single most important factor in how a suit jacket looks and feels.
The Fit Checklist
- Shoulders: Seam sits exactly at the edge — not hanging over, not pulling inward
- Chest: Lies flat when buttoned with no pulling or creasing
- Length: Hem covers your seat, falls at the knuckle of your thumb
- Sleeves: Show ½ inch of shirt cuff below the jacket sleeve
- Waist: A slight taper creates a clean, masculine silhouette
“An expensive jacket in the wrong size will always look worse than a modest jacket that fits perfectly.”
Chapter 06
Fabric & Seasonality
Dress for the Climate
The finest jacket is one that suits not just the occasion, but the season. Investing in jackets across multiple fabric weights ensures you are never overdressed for the temperature — and always impeccably dressed for the moment.
Final Word
Invest in Fewer,
Better Pieces
The modern gentleman does not need a wardrobe of dozens of jackets. He needs five exceptional ones — each chosen with intention, each fitting perfectly, each serving a clear purpose.
Start with navy. Add charcoal. Build from there.
At Aesido, every jacket is crafted with precision tailoring, premium fabrics, and an unwavering commitment to the details that matter. Because the right jacket doesn't just complete an outfit — it defines the man wearing it.
